I really need some good suggessions... Thanks

Is there any option to check somatic variant, by the use any probe based technologies?

I think you can use allele specific PCR, or if the mutant allele frequency is not too low even Sanger sequencing can give you a quick validation.

According to market study performed by Ghent University spin-off company pxlence, 56% of scientists (n=200) validate their NGS findings with Sanger sequencing. pxlence has PCR assays for the entire human exome.
